badassBox for PENDIX motors


Pendix motors use very specific speed sensors, whose shape and positioning decide on the badassBox to be used.

Where is your sensor?

The speed sensor and its positioning are decisive for which badass box you need.

We distinguish between the classic mounting on the chain stay and the integrated mounting in the area of the dropout.

Sensor on the chain stay

A good indication that your sensor is on the chain stay is the presence of a spoke magnet.
In addition, the sensor is usually direct and easily visible.

Pendix Sensor

If this sensor of your Pendix motor - as shown in the picture below - is located on the chain stay of your bike, then the badassBox4 Pendix is exactly what you need.

badassBox 4 Pendix
Attention, the new Pendix sensor (second picture) is not compatible! Badass eBikes proudly presents: the new improved badassBox 4 Pendix The badassBox 4 is the result of more than a year's development. We have completely re-designed the casing, made it more streamline and replaced the o-ring of the previous version with our patented snap-lock fastening. Making it more streamline makes it even easier to fit. The new snap-lock fastening means you can attach and remove your badassBox with just one hand in seconds. At customer's request, we have additionally added an optional securing feature on the snap lock using a cable tie. The CR2 battery has been replaced with a AAA battery, so you can pick up replacement batteries much cheaper on just about any street corner. Tool-free battery change can be carried out quickly and easily while you're on the road.We recommend replacing the battery at least once a year at the start of the season. Due to our specially patented field enhancement technology FEET (Field Enhancement & Elimination Technology) you get very far with one battery. To protect against moisture and mechanical stress, the electronics are glued into the casing and completely sealed with a special casting compound. The badassBox is developed and manufactured exclusively by us in-house. Before and after casting we check each badassBox individually. Customer satisfaction and quality are our top priorities. If you have any questions, don't hesitate to ask – we'll get back to you with an answer straightaway, mostly on the same working day. Due to the high quality and our focus on customer satisfaction, we additionally offer a 1 month money-back guarantee. In a nutshell The badassBox is attached to the speed sensor of the e-bike and overrides the 25 km/h speed limit. Remove it and your e-bike is restored to its original state. Contactless e-bike tuning Streamlined, registered design for casing Patented snap-lock fastening Securing feature on the housing Patented field enhancement technology Auto industry potting compound Doubled quality control Made in Germany One month money-back guarantee Installation You will find the speed sensor on the chainstay of your bike (as pictured). The badassBox 4 Pendix is fitted over the Pendix speed sensor next to the rear wheel. When the snap-lock clicks into position, the badassBox is fitted securely to the sensor. For extra secure fitting, the badassBox can also be fastened with a zip tie. Once the badassBox has been fitted onto the sensor, the spoke magnet must be offset to the casing edge in the direction of the snap-lock clasp. It's now ready for use. Following removal of the badassBox, the spoke magnet must be returned to its original position. .responsive-video { position: relative; padding-bottom: 56.25%; padding-top: 30px; height: 0; overflow: hidden; } .responsive-video iframe { position: absolute; top: 0; left: 0; width: 100%; height: 100%; } How it works The contactless and wireless badassBox transmits a modified signal in order to override the speed limit of your e-bike – without interfering with the motor's electronic circuitry or software. There's no need to open the motor and there is no risk of damaging it. The badassBox can be fitted in seconds – and just as quickly removed, restoring your e-bike to its former road-legal condition. For all these advantages, a wrong speed, and values derived from it, are displayed. We recommend the use of GPS-related accessories for a more precise data acquisition of driving data (smartphone, bike computer, etc.).
